When I first played D&D with David maybe 3 Christmases ago, one of the most baffling things for me to understand was my character sheet. Take a looka t the first page of Sam’s Dungeon in a Box character sheet:

Ignoring how busy this page is, one of the biggest design issues I see right away is that all of the trait boxes are incorrectly prioritized. I have seen people argue for completely eliminating the scores from the sheet because you don’t ever use those scores. Instead, you use the modifiers (the +# or -#). Yet on this sheet those numbers are teeny, tiny compared to the numbers that are functionally useless. (Except during character creation) I would otherwise say there’s not too much that’s bad about this page - it gives you the information you will need most often. The second page has information you might need to refer to so that you don’t need to keep referring to the Player’s Handbook (PHB)
